Subject[PATCH v2 0/2] Add interconnect driver for SDX55
Date
Hello Georgi,

This small series adds interconnect driver support for SDX55 platform for
scaling the bandwidth requirements over RPMh. The driver has been tested
on SDX55-MTP and gives below DDR metrics using mbw [1] tool:

Src port: SDX55_MASTER_AMPSS_M0
Dest port: SDX55_SLAVE_EBI_CH0

Command: mbw 100

With bandwidth 500000:
AVG Method: MEMCPY Elapsed: 0.59058 MiB: 100.00000 Copy: 169.324 MiB/s
With bandwidth 700000:
AVG Method: MEMCPY Elapsed: 0.29267 MiB: 100.00000 Copy: 341.678 MiB/s
With bandwidth 900000:
AVG Method: MEMCPY Elapsed: 0.19608 MiB: 100.00000 Copy: 510.005 MiB/s

The copy speed seems to be the same for all bandwidth less than 500000 and
greater than 900000.

Note: The CPUFreq governer needs to be set to something other than schedutil to
see the difference. Otherwise the speed seems to be the same for all bandwidth.

Thanks,
Mani
